Miniature rose plant named &#39;Poulty014&#39;

ABSTRACT

A new miniature rose plant that has abundant, yellow flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL DESIGNATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulty014’

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenthe female seed parent, an unnamed seedling, and the male pollen parent,also an unnamed seedling.

The two parents were crossed during the summer of 2007 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulty014’, originated as a single seedling fromthe stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by flower coloration and growth habit.

The objective of the hybridization of this rose variety for commercialculture was to create a new and distinct variety with unique qualities,such as:

1. Uniform and abundant yellow flowers;

2. Vigorous and compact growth;

3. Year-round flowering under glasshouse conditions;

4. Suitability for production from softwood cuttings in pots;

5. Durable flowers and foliage which make a variety suitable fordistribution in the floral industry.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulty014’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization and conducted evaluations onthe resulting seedlings in a controlled environment in Fredensborg,Denmark. ‘Poulty014’ was selected by the inventor as a single plant fromthe progeny of the hybridization in 2007.

Asexual reproduction of ‘Poulty014’ by cuttings was first done by MogensN. Olesen in the nursery in Fredensborg, Denmark in 2008. This initialand other subsequent propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘Poulty014’ are true totype and are transmitted from one generation to the next.

DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of ‘Poulty014’.Specifically illustrated in the drawing are flowers at various stages ofdevelopment, flower in parts, leaves, and stems.
